surgical instrument 1 of the “KERRISSON” forceps or rongeur type comprising a main body formed of afixed handle 2 on which afixed jaw 3 is fixed in a roughly horizontal plane. - The
surgical instrument 1 comprises amoving handle 4 which pivots about an axis ofrotation 5 passing through thefixed handle 2 for the longitudinal movement of a movingjaw 6. - The
moving handle 4 is connected to thefixed handle 2 by a leaf-shaped spring 7 to place themoving handle 4 in a single starting position after each pivoting action. - The
fixed jaw 3 of thesurgical instrument 1 collaborates with the movingjaw 6 which slides in the longitudinal direction guided back and forth on said fixedjaw 3 when force is applied to themoving handle 4. - FIG. 2 shows the
fixed handle 2 of thesurgical instrument 1 which is secured in its upper part and in a horizontal direction to fixing means which consist of a hollowcylindrical sleeve tube 8. - The
cylindrical sleeve tube 8 comprises aninternal bore 9 open at both ends and communicating with aslit 10 of conical profile formed in the thickness of the upper part of the fixed handle. - The
slit 10 is delimited byopposed edges cylindrical sleeve tube 8. - The
fixed handle 2 comprises, on each side of theslit 10, alug 13 in the shape of a portion of a circle pierced with abore 14 in the shape of a keyhole intended to accommodate the axis ofrotation 5 for guiding the rotation of themoving handle 4. - The maximum travel of the
moving handle 4 about the axis ofrotation 5 inside theslit 10 of thefixed handle 2 is delimited by theopposed edges - The
cylindrical sleeve tube 8 is given a length greater than that of the upper part of thefixed handle 2 so that each free end of said sleeve tube is easy to access. - The
cylindrical sleeve tube 8 comprises at one of its ends a threadedcollar 15 delimiting ashoulder 16 in which cut-outs 17 are made, uniformly distributed around the peripheral perimeter of said sleeve tube. - FIG. 3 illustrates the
moving handle 4 of thesurgical instrument 1 which has a cranked profile consisting of afirst branch 18, of short length, extended by asecond branch 19, of longer length. - The
first branch 18 is extended at the opposite end to thesecond branch 19 by amounting plate 20 forming a fork pierced with abore 21 which communicates with an openoblong slit 22. - The
bore 21 has a diameter slightly greater than that of theoblong slit 22. - The bore-21 is designed to accommodate the axis of
rotation 5 so that themoving handle 4 can pivot about this axis when mounted in theslit 10 of thefixed handle 2 of thesurgical instrument 1. - It will be noted that the free end of the
oblong slit 22 formed in themounting plate 20 opens into thebore 9 of thesleeve tube 8 of thefixed handle 2 to collaborate with the movingjaw 6. - FIGS. 4, 5 and11 depict the
fixed jaw 3 of thesurgical instrument 1, which jaw consists of acylindrical tube 23 secured at one of its ends to acontinuation 24 in the form of an elongate mounting plate that has a U-shaped solid cross section. - The
continuation 24 comprises, at its free end, anose 25 having, in its thickness, a hollowing 26 delimitingopposed edges 27 which are inclined with respect to theupper edge 28 of said continuation. - The
edges 27 of thenose 25 are machined to constitute cutting elements so as to cut bone fragments. - The
continuations 24 comprise, near thenose 25, a T-shaped tenon 29 allowing longitudinal guidance of the movingjaw 6 along its entire travel. - The
continuation 24 comprises on its twofaces graduations 57 intended to guide the operator in the endoscopic operations. - The
continuation 24 comprises, at the opposite end to itsnose 25, ashoulder 30 which enters the lower part of thecylindrical tube 23 and part of the shoulder of which is welded into said tube to form a rigid and firm connection. - The
upper edge 28 of thecontinuation 24 comprises, at theshoulder 30 and inside thetube 23,lateral stops 31 delimiting, on the central axis of thefixed jaw 3, aslot 32 for the longitudinal guidance of the movingjaw 6. - The upper edges of the
lateral stops 31, parallel to theedge 28, delimit the opening of theinternal bore 33 of thetube 23 at theextension 24 of thefixed jaw 3. - The
shoulder 30 comprises anelongate part 34 which is arranged inside thebore 33 and above theinternal wall 35 of thecylindrical tube 23 making it possible to delimit aslot 55 of curved profile which communicates with ahole 36 opening to the outside of said tube. - The
hole 36 is to enable pressurized products to be injected to clean thebore 33 of thetube 23 forming the fixedjaw 3. - The
tube 23 of the fixedjaw 3 comprises on its external perimeter and at the opposite side to thecontinuation 24, acylindrical shoulder 37 secured to astop 38. - The
tube 23 comprises, at theshoulder 37, anut 39 provided in its internal part with ashoulder 49 allowing thestop 38 to pass (FIG. 8). - The fixed
jaw 3 is fixed on the fixedhandle 2 when thestop 38 collaborates with the corresponding cut-out 17 and thenut 39 screwed onto thecollar 15. - In a second version shown in FIG. 12, the
tube 23 of the fixed jaw comprises on its external perimeter and at the opposite side to thecontinuation 24, a cylindricaldouble shoulder 37, part of which has aslit 61. - This slit corresponds with a
stub 60 provided on anelastic ring 59 so as to immobilize this ring around theshoulder 37. - The
tube 23 at thedouble shoulder 37 comprises anut 39 provided in its internal part with ashoulder 49 allowing the passage of theelastic ring 59 mounted without impeding its radial expansion. - The fixed
jaw 3 is fixed on the fixedhandle 2 when anindexing finger 62 of theelastic ring 59 collaborates with one of the cut-outs 17 of theshoulder 16. - Thus it can be seen that the
shoulder 16 of the fixedhandle 2 has different cut-outprofiles 17 which may be either radial or axial depending on the usage of thesurgical instrument 1. - It can be seen that the fixed
jaw 3, and more particularly itsnose 25, can be arranged in different planes about its horizontal axis according to the surgeon's choice and the operation that is to be performed, depending on which angular position of cut-out 17 is adopted on the periphery of thesleeve tube 8 for securing this fixedjaw 3. - FIGS. 6 and 7 show the moving
jaw 6 which consists of acylindrical tube 40 comprising an openinternal bore 41 into which there is welded, at one of the ends of said tube, acontinuation 42 forming an elongate mounting plate the hollow cross section of which is in the form of an inverted U. - The outer edges43 of the continuation along the entire length of the
continuation 42 delimit aninternal passage 44 in the shape of an inverted U, the base of which is open. - The
continuation 42 at its free end comprises inclined andopposed edges 45 which are beveled, outward on the one hand with respect to theouter edge 43 and toward the inside of thepassage 44 on the other. - The
passage 44 comprises, near theinclined edges 45, opposedribs 46 separated by aslit 47 so as to form a slideway collaborating with the T-shapedtenon 29 of thecontinuation 24 of the fixedjaw 3. - On the opposite side to the
inclined edges 45, thecontinuation 42 has ashoulder 48 welded into the upper and internal part of thecylindrical tube 40 to form a rigid and firm connection. - The inverted U-shaped
internal passage 44 opens into theinternal bore 41 of thecylindrical tube 40 so that its open base faces toward the lower part of said tube. - It will be noted that the internal profile of the
passage 44 increases from theinclined edges 45 to the end of theshoulder 48. - It will be noted that the
internal passage 44 is designed to constitute a store to store the bone fragments 56 cut using thebeveled edges - The
cylindrical tube 40 is secured on the opposite side to theextension 42 to acylindrical ring 50 the outside diameter of which exceeds that of said tube. - The
ring 50 consists of afirst part 51 with a knurled surface for holding the movingjaw 6 and of asecond part 52 provided withoblong housings 53 in which drivespindles 54 are fixed. - The
oblong housings 53 are uniformly distributed about the periphery of thering 50 in angular directions which are the same as those intended for the cut-outs 17 made in the periphery of thesleeve tube 8 of the fixedhandle 2. - The oblong cut-
outs 53 are made parallel to the longitudinal axis of the movingjaw 6, while thedrive spindles 54 fixed in each housing are directed in a direction perpendicular to the longitudinal axis. - Before the moving
jaw 6 is set in place inside the fixedjaw 3, the movinghandle 4 is mounted in the fixedhandle 2 by means of the axis ofrotation 5 so that its oblong slit 22 is directed in a direction toward the rear of the instrument (FIG. 8). - The moving
jaw 6 is introduced into thesleeve tube 8 secured to the movinghandle 2 and on which thenut 39 is mounted for fixing the fixedjaw 3. - The
continuation 42 of the movingjaw 6 sits above that 24 of the fixedjaw 3 so that theribs 46 and theslit 47 collaborate with thetenon 29 provided near the nose 25 (FIG. 10). - Also while the moving
jaw 6 is being set in place, it can be seen that theouter edges 43 are guided in thegroove 32 provided on theshoulder 30 of thecontinuation 24 of the fixedjaw 3. - The moving
jaw 6 is automatically indexed into an angular position by the guide means 29, 46, 47; 32, 43 according to the position of the fixedjaw 3 with respect to the fixedhandle 2 so that one of thedrive spindles 54 of thering 50 enters theslit 22 of the moving handle 4 (FIG. 8). - FIGS. 6b and 7 b show an alternative form of the
ring 50 of the movingjaw 6 which consists in forming just oneoblong housing 53 and just onedrive spindle 54. - Here, the tube of the moving
jaw 6 is free to rotate about thering 50 allowing the moving jaw to position itself automatically according to the angular indexing of the fixedjaw 3 relative to the fixedhandle 2. - For example, the
tube 40 is crimped onto thering 50 after a runningband 58 that allows the tube to rotate with respect to thering 50 has been fitted. - Finally, a hard point will allow the
oblong housing 53 to be brought back along the axis of thetunnel 44 to make it easier to introduce the movingjaw 6, the fixedjaw 3 being oriented on the fixedhandle 2 beforehand. - The moving
handle 4 has various angular operating positions determined by the lateral displacement of the axis ofrotation 5 as described either inpatent EP 1 075 220 or in patent PCT/FR99 01528 of which the applicant is proprietor. - FIGS. 9 and 10 show the longitudinal movements in operation of the moving
jaw 6 with respect to the fixedjaw 3 of thesurgical instrument 1 when the surgeon operates the movinghandle 4. - FIG. 10 depicts the
surgical instrument 1 in its wide open position, that is to say when thebeveled edges 45 of the movingjaw 6 are the furthest from those 27 of thenose 25 of the fixedjaw 3. - In this wide open position, it can be seen that the lower part of the
cylindrical tube 40 of the movingjaw 6 collaborates with the slot ofcurved profile 55 delimited by theinternal wall 35 of thetube 23 and theelongate part 34 of theshoulder 30 of thecontinuation 24 of the fixedjaw 3. - Again in this wide open position, it will be noted that the
tenon 29 for guiding thecontinuation 24 of the fixedjaw 3 still collaborates with theslit 47 delimited by theribs 46 of thecontinuation 42 of the movingjaw 6. - FIG. 10 illustrates the
surgical instrument 1 in its closed position, that is to say when thebeveled edges jaw - In this position, the surgeon has just cut a piece of
tissue 56 or bone which is collected inside theinternal passage 44 of thecontinuation 42 of the movingjaw 6, before this jaw returns through elastic return to the open position described and shown in FIG. 9. - Thus, the surgeon, by repeated movements on the moving
handle 4, can move the movingjaw 6 with respect to the fixedjaw 3 between a wide open position and a closed position allowing him to cut thebone tissue 56. - These repeated actions allow the uniform and successive cutting of
bone tissue 56 causing theinternal passage 44 that forms a store for the storage of cut pieces gradually to become filled. - It can be noted that the
cut pieces 56 are held laterally by the internal walls of thepassage 44 of thecontinuation 42 of the movingjaw 6 and by theupper edge 28 of thecontinuation 24 of the fixedjaw 3. - As successive cuts are made by the surgeon, the
passage 44 gradually fills and so it is essential for this passage to have sufficient capacity and also for thecut pieces 58 not to prevent the sliding of the movingjaw 6 with respect to the fixedjaw 3. - It can be seen that the
cut pieces 56 contained in thepassage 44 are pushed into this passage each time theinstrument 1 is closed, by the next piece cut by thebeveled edges - These successive cutting operations will gradually convey the first cut pieces into the
cylindrical tube 40 of the moving jaw, where the internal space delimited by thebore 41 is greater than the space in thepassage 44. - Collecting the
cut pieces 56 in theinternal bore 41 makes it possible never to impede the sliding of the movingjaw 6 on the fixedjaw 3 because of the difference in size between said bore and thepassage 44. - What actually happens is that the
cut pieces 56 move smoothly along thepassage 44 and along theupper edge 28 of the fixedjaw 3 and then become lodged in thebore 41 of the moving jaw 6 (FIG. 9). - Thus, the
internal bore 41 of thetube 44 of the movingjaw 6 constitutes a large-capacity second store allowing the surgeon no longer to have to remove thesurgical instrument 1 from the operating site with each cutting stroke. - It must also be understood that the foregoing description has been given merely by way of example and that it does not in any way restrict the field of the invention, a departure from the scope of which would not be made if the embodiment details described were replaced by any other equivalent.
